Nested homotopy models of finite metric spaces and their spectral homology

Abstract For over a decade, two theories have been actively developed: theory of magnitude and magnitude homology of metric spaces, and GLMY-theory of path homology of directed graphs. Recently Asa...

Flexible varieties, images of affine spaces, and ellipticity after Mikhail Gromov

Abstract We define flexible affine algebraic varieties, describe their basic properties, and show that many varieties satisfy the flexibility condition. The group of special automorphisms acts in

General behavior ofarea-minimizing subvarieties

Abstract We will review some recent progress on the general geometric behavior of homologically area-minimizing subvarieties, namely, objects that minimize area with respect to homologous

Applications of o-minimality to Hodge theory IV | Algebraic and Complex Geometry Seminar

Abstract The goal of this minicourse is to introduce the recent advances in Hodge theory via o-minimal techniques. We will start by revisiting the basics on o-minimal geometry with a view towards

BIMSA General Lecture | Harnessing The Collective Wisdom: Fusion Learning Using Decision Sequence...

Abstract Learning from the collective wisdom of crowds enhances the transparency of scientific findings by incorporating diverse perspectives into the decision-making process. However, fusing

Igusa stacks and exotic Hecke correspondences

Abstract Title I: Igusa stacks and exotic Hecke correspondences I Abstract: Igusa stacks are conjectural p-adic analytic objects related to Shimura varieties, which were conjectured to exist b
